You MIDI "hardware" and your MIDI "controller" already have computers inside, both with software. They just do not run conventional OS, but for modern hardware even that is not always true.
Based on your replies, probably you would prefer something like: http://www.midisolutions.com/prodepp.htm
I do not have it, but I understand how it works. Also I have just checked that installer and the software is completely accessible. Note that linked device support up to 32 mappings. So you can map up to 32 controls only, not more.
Sorry, but if the price and/or the number of parameters is not acceptable, you will need sighted help to setup the controller or use computer based translation.
"Computer based" does not mean you need a notebook... can be Raspberry PI or Intel based TV box. The setup will be rather technical.
Sighted help can be in different directions:
* setup the hardware every time you need on the hardware
* prepare several presets in software, so you can upload required to the controller with HSC or similar tool
* make preset editor accessible... f.e. using Sibiac overlay
